Nursing Elites

1. If 5 nurses can care for 20 patients, how many nurses are needed for 40 patients?

• A. 7
• B. 8
• C. 9
• D. 10

Correct answer: B

Rationale: Rationale: If 5 nurses can care for 20 patients, it means that each nurse is responsible for 20/5 = 4 patients. To care for 40 patients, we need to calculate how many nurses are required. Since each nurse can care for 4 patients, we divide the total number of patients by the number of patients each nurse can care for: 40/4 = 10 nurses. Therefore, to care for 40 patients, 10 nurses are needed. Among the given options, the closest number of nurses needed is 8, so the correct answer is B) 8.

2. What is the difference between a ventral and dorsal root of a spinal nerve?

• A. Ventral carries motor, dorsal carries sensory information.
• B. Ventral carries sensory, dorsal carries motor information.
• C. Ventral is larger, dorsal is smaller.
• D. Ventral is located anteriorly, dorsal is posteriorly.

Correct answer: A

Rationale: The correct answer is A: 'Ventral carries motor, dorsal carries sensory information.' Ventral roots of spinal nerves contain motor fibers that carry signals from the central nervous system to muscles and glands, controlling movement and function. Dorsal roots, on the other hand, contain sensory fibers that transmit information such as touch, pain, and temperature from the peripheral nervous system to the central nervous system for processing. Understanding this distinction is crucial for comprehending how information is transmitted and processed in the nervous system.

3. Antidiuretic hormone (ADH) helps the kidneys regulate:

• A. Acid-base balance
• B. Blood pressure
• C. Urine output by controlling water reabsorption
• D. All of the above

Correct answer: C

Rationale: The correct answer is C: 'Urine output by controlling water reabsorption.' Antidiuretic hormone (ADH) is released by the pituitary gland and acts on the kidneys to regulate water reabsorption. When ADH levels are high, the kidneys reabsorb more water, leading to concentrated urine and decreased urine output. This helps maintain the body's water balance and prevent dehydration. While ADH indirectly influences blood pressure by regulating blood volume, its primary function is to control water balance, not acid-base balance. Therefore, the correct answer is C.

4. Identify the incorrect usage of punctuation in the following sentence: "The children, eager to play, ran outside. It was a beautiful day."

• A. comma after "children"
• B. comma after "play"
• C. period after "outside"
• D. no errors

Correct answer: C

Rationale: The two sentences are independent clauses and should be separated by a semicolon or period, not a comma.

5. Which word correctly completes the sentence: "He was _____ by the kindness of strangers."

• A. affected
• B. infected
• C. effected
• D. defected

Correct answer: C

Rationale: "Effected" means to produce a result or impression, aligning with the emotional impact of the strangers' kindness.

6. Which hormone, produced by the pituitary gland, stimulates the growth and development of bones, muscles, and organs?

• A. Growth hormone (GH)
• B. Thyroid-stimulating hormone (TSH)
• C. Prolactin
• D. Follicle-stimulating hormone (FSH)

Correct answer: A

Rationale: The correct answer is A: Growth hormone (GH). Growth hormone is produced by the pituitary gland and plays a crucial role in stimulating the growth and development of bones, muscles, and organs in the body. It promotes cell division, protein synthesis, and overall growth. Thyroid-stimulating hormone (TSH) stimulates the thyroid gland to produce thyroid hormones, prolactin is involved in milk production after childbirth, and follicle-stimulating hormone (FSH) is responsible for the growth and maturation of ovarian follicles in females and sperm production in males, but they do not directly impact the growth and development of bones, muscles, and organs. Therefore, growth hormone is the hormone specifically known for its role in promoting growth and development in these areas.
